Don't let this happen to you... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just wanted to share this so nobody else is chasing their tail trying to figure this out. I took the truck out yesterday for a drive. All of a sudden it sputtered,i hit the gas , and died. I thought the alternator the gone bad and that the truck just drained the battery until It had no juice left. I tried to restart the truck, nothing. I turned the lights on and got to see if they were on...nothing. had it towed home. Today I figured out that there was a bad connection where the engine harness connector went into the connector near the brake booster mounted in the upper left-hand corner of the firewall. The main power coming from the battery goes through that connector and into the truck which distributes power throughout the electrical system. I cleaned the connections with some detoxit which is a really good contact cleaner I use when fooling with guitars and guitar amps. Used a little Dielectric grease on the connectors as well and put it all back together, no issues,starts right up runs as it should.

Good info 64stpside. Some of those connections have been there 40 years so it's a great reminder to do some cleaning before it happens.

Thanks for the tip.
I replaced my tail light bulbs a couple days ago. I had to use PB Blaster just to get them out.
